10-Year Transmission Assessment
Summary• Need categories (definitions of project need drivers)• Planned, proposed and conceptual projects (tables showing projects
by year, by project type and by zone)• Estimated capital costs of projects
Summary of Planned, Proposed and Conceptual Additions, 2003-2012
The facilities proposed by the ATC based on this 2003 Assessment arelisted in Tables VI-1 through VI-19, and shown graphically by zone inFigures VI-1 through VI-5. In addition, alternatives for some theprimary alternatives shown in Tables VI-1 through VI-19 are listed inTable VI-20. Also, portions of the plan in the 2002 Update Assessmentthat are not included in this plan are listed in Table VI-21.
In each of these tables, there is a column indicating the planned inservice year for each particular facility and a column indicating theyear the facility is needed. There are numerous facilities for which theyear it is needed precedes the planned in service year. There are avariety of reasons for this, including:• The preferred alternative to address a particular need may take
several years to implement.• The need may have existed but had been addressed with
operating procedures that are becoming less effective orineffective.
• The preferred alternative to address a particular need may needto be implemented in phases, thus delaying certain phases.
• New data or information became available that affected thenature of the need or limitation, which necessitated a change inthe alternative to be implemented, introducing a delay inimplementation.
• The need for a project was based on load or generationdevelopment that was uncertain.
• Stakeholder input necessitated a change in the alternative to beimplemented, introducing a delay in implementation.
Tables VI-1 through VI-10 show the facilities planned by year for2003-2012 respectively. Tables VI-11 through VI-15 show thefacilities planned by zone. Table V-16 provides a list of plannedtransmission lines involving new right-of-way for 2004-2012. SinceATC intends to solicit public input on the identification of ultimatesolutions through its iterative planning process, these particularprojects may be modified in the future. Table V-17 provides a list ofproposed transmission line rebuilds, reconductoring and uprates onexisting right-of-way. Table V-18 provides a list of proposed newsubstations and transformer additions (excluding transmission-to-distribution transformers). Table V-19 provides a list of otherproposed substation equipment additions or replacements.
Need CategoriesWithin the above tables, the need for each project is identified. Needcategories include the following:
Reliability: Facility (line, transformer, substationequipment) normal rating is exceededunder normal system conditions oremergency rating is exceeded under singlecontingency conditions, or bus voltage isnot within 5% of nominal voltage undernormal system conditions or is not within10% of nominal voltage under singlecontingency conditions. (see Appendix C)Impending overload or voltage violationsare noted as appropriate.
New generation: Facility has been identified as necessary toaccommodate new generation in generationinterconnection studies and relatedtransmission service studies conducted byATC.
TLR: Facility has been identified by ATCOperations or ATC Transmission Service asa chronic cause for interrupting, curtailing,limiting or denying transmission service inreal time.
T-D interconnection: Facility is required to interconnect to a newtransmission-distribution substationneeded by a distribution company servedby ATC.
Condition: Facility has been identified by ATCMaintenance as being in need of repair orreplacement.
Stability: Facility has been identified by ATC Stabilityand Special Studies as needed to ensureATC dynamic stability criteria is met (seeAppendix C), or will improve stabilityresponse of generation.
Import capability: Facility will enhance import capability ofthe ATC transmission system.

Typical Transmission Line and Substation Capital CostsTo provide some perspective of the cost implications of projectalternatives included in this Assessment, ATC has compiled capitalcosts for various types of projects that are representative of themagnitude of such types of projects. These typical capital costs arelisted in Table VI-22.
It should be noted that the costs listed are merely representative forprojects within each category. Actual project costs can vary, in somecases dramatically, based on the scope, location and particular designof the project. Capital costs include material, labor, licensing, design,land acquisition, environmental mitigation fees if applicable andproject close-out. While some projects require additional costs ofgenerator redispatch during construction outages, such cost are veryproject specific and have not been included in the estimates below.Regarding the categories below:
• New transmission line cost is shown per mile.• Rebuilt transmission line cost is shown per mile.• Reconductored transmission line cost is shown per mile.• New substation costs are shown as per terminal at each voltage.
Routing an existing transmission line into a new substationtypically requires two terminals, particularly at 100 kV and above.Installing a new transformer in a substation requires twoterminals, one at the higher voltage and one at the lower voltage.Thus, a new 345-138 kV substation that incorporates an existing345 kV line and two 138 kV transmission lines, all of which existnear the new substation site, would require three 345 kV terminalsand five 138 kV terminals.
• Transformer costs are shown for typical transformer sizes in eachclass (500 MVA for 345/138 kV and 345/115 kV; 100 MVA for138/69 kV and 115/69 kV).
